STARGARDT FLOOR CONVEYER FOR Tmicks Filed July 29, 1940 2 Sheets-Sheet 2 l/VVE/Y 7-022 Hrlen Sta/ Patented Apr. 19 42 UNITED STATE S PATENT OFFICE 1 w noon comma Foa ravens Helen Stargardt, Detroit, Mich. Application July 29, 1940, Serial No. 348,218 1 Claim. (01. 214-83) The present invention relates to improvements in trucks and has for its object the provision of a floor constructed in the form of a conveyer belt and which may be operated by the truck motor or may be manually operated.

The object of the invention is to save hand lifting of lumber and heavy articles in loadin and unloading the truck.

Another advantage of the invention is that by removing the body of the truck it may be readily applied to any kind of truck with minimum ex- With the foregoing in mind, it will become readily apparent that'the invention possesses further advantages, all of which will be clearly K revealed during the course ofthe following deby the truck motor. and also manually operated means therefor.

a Figure 4 is a partial side elevation of theinven- Figure 5 is a rear elevation of the complete invention.

The invention consists of longitudinally extending frame I which is secured to chassis frame 2', and referring to Figure 1 the truck cab 'isshown at 8', motor 4, wheels I, differential 6; propeller shaft housing I and fender 8, also radiator 8 where indicated.

The floor of the truck consists of an endless belt having spaced apart slats "which are flexibly connected together by links ll, said belt is adapted to engage specially designed sprocket drums l2, said drums are mounted upon transverse shafts i3 respectively, said shafts are also Journaled within bearings it where shown.

Referring to Figure 3 it is seen that the floor conveyer may be operated by motor l in the following manner':

The crankshaft of motor 4 is shown at it and has sprocket wheel i! keyed thereto as shown, an additional sprocket wheel i1 is provided and is mounted upon shaft It with bearing it therefor, also chain connecting sprocket wheels It and I1. Bevel gear 2| is secured to shaft I8 and meshes with bevel gear 2! upon shaft 23, also manually operated clutch 24 being provided where located.

Additional sprocket wheels 25 and 26 are provided and are connected by chain 21. wheel 25 is keyed to shaft l3.

Clutch 24 is operated from the drivers seat,

but this control is not indicated in the drawings. The floor conveyer is operated manually as Sprocket 3 follows:

Still referring to Figure 3, gear 29 being keyed to shaft it within the rear of the apparatus, gear 30 is provided and meshes with gear", bearing ll being for shaft 32 upon which gear II is connected. Shaft 32 has square end It thereon for the application of a crank (not shown).

By manually operating shaft "the floor conveyer may be actuated as slow as desired. thus facilitating loading and unloading of the truck.

Again referring to Figure 3; shaft, I3 is broken fur the reason that the power control of shaft ll in loading and unloading the truck, it also reis at the front of the apparatus nearest motor 4, while the manually operating means of shaft I II is at the rear of the apparatus.

The useof this invention will save much time lievesthe operator of the burden and hazard of much hand lifting, requiring a less number of persons for this work, hence the advantage of the invention from a safe and economical viewpoint.

In conclusion, let it be understood that the complete disclosure herewith is merely illustrative of the general principle of the invention sought to be protected by Letters Patent, and

any contemplated changes made therein that would fall directly within the scope of the claim. Having thus fully described my invention, what Iclaimasnewis:

' shafts carrying the same and formed with with In a floor conveyer for trucks, a frame. a drive shaft, a driven shaft, said shafts being located at opposite ends of the frame, drums carried by said shafts and turning with the shafts, said, drums being of appreciably less length than the tudinally extending radial ribs spaced from each other'circumferentially of the drum. and an end-' less carrier extending longitudinally in the frame and having'upper and lower flights and portions trained about the drums, said carrier consisting of transversely extending slats having end portions projecting from the ends of the drums, and rings engaged through side edge portions of the slats outwardly of the ends of-the drums and connecting the slats in spaced relationto each other, the slats being of a width adapting them to fit between the 'ribs of the. drums with the slats resting against the drums and the ribs passing through the spaces between the slats and engaging the side edges of the slats. i
